T/CPCIF 0038-2020 Green Design Product Evaluation Specification Polyethylene terephthalate (PET) Resin

Scope

Scope: This standard specifies the terms and definitions, evaluation principles and methods, evaluation requirements, and preparation methods for life cycle assessment reports of green design products made from polyethylene terephthalate (PET) resins. This standard applies to the evaluation of green design products made from polyethylene terephthalate (PET) resins produced by the direct esterification process; Main technical content: Based on the principle of combining life cycle assessment with indicator evaluation, considering the entire life cycle of polyethylene terephthalate resin products, from product design, raw material acquisition, product production, product use, post-disposal recycling, and comprehensive utilization of industrial wastewater, etc., we conduct in-depth analysis of resource and energy consumption, ecological environment, and human health factors at each stage. We select indicators that can be evaluated at different stages to form an evaluation indicator system. Based on the characteristics of polyethylene terephthalate resin products and production processes, and considering the high social attention and the types of environmental impacts explicitly required by national laws or policies, we select key resource attributes, energy attributes, environmental attributes, and product attributes for evaluation. This technical specification selects indicators such as raw material unit consumption, fresh water usage, waste recycling and resource utilization rate, comprehensive energy consumption per unit product, wastewater discharge per unit product, and harmless disposal rate of organic wastewater, purity, moisture, heavy metals, and carbonyl number for evaluation.
